Complex Feature Requests

Remember image URLs (#163)

• Remember every image ripped, save to file (or history?)
• Store URLs in history, use stored URLs to avoid duplicates
• Ability to clear URLs to re-rip all images

Stop ripping already-ripped content (#73 #76)

• Basic idea: Re-ripping a site should stop when we hit content that we've already gotten, i.e. ripping a subreddit (sorte by new), tumblr page, etc.
• Could be a boolean in AlbumRipper
• Note: Need to watch out for reposts/false-duplicates (same URL but hasn't been ripped before)
• Could be alleviated by storing the most-recent timestamp (reddit and tumblr expose the timestamp in their APIs).

Subscriptions (#162, #176, #190)

• Re-rips the album every X minutes/hours.
• Could be another checkbox or "clock" icon in the History page.
• Clicking the "clock" would show a prompt ("How often should this album be re-ripped?")
• Or a Subscribe button below everything else.
• Or a right-click popup menu to "Subscribe: X minutes" and "Unsubscribe"
